This invention relates generally to controlling the locking and unlocking of doors; and more particularly concerns provision of highly compact and improved mechanism for enabling operating of latches and deadbolts, as from opposite sides of doors.
There is need for simple, highly compact, durable and efficient door locking and unlocking devices, where deadbolts and latches are to be operated, as from the inner and outer sides of doors. In particular, there is need for improvements in mechanism responsive to door handle turning, at the door inner side, with mechanism responsive to door unlocking at the door inner side, to secure both deadbolt release and door unlatching.
SUMMARY OF THE INVENTIONIt is a major object of the invention to provide improvements on apparatus meeting the above needs. Basically, and in accordance with the invention, a multi-function door lock system is provided, comprising:
a) a frame having opposite sides, and installable on a door openable between an interior space and an exterior space,
b) a deadbolt and a door latch carried by the frame to move between retractable and extended positions,
c) a first rotary control located at one level on the frame to control deadbolt movement between extended and retracted positions via primary cam mechanism,
d) a second rotary control at another level on the frame to control latch movement between extended and retracted positions, via secondary cam mechanism,
e) means operatively connected between said secondary cam mechanism and said primary cam mechanism to effect deadbolt movement as aforesaid, in response to operation of the second rotary control, as effected via rotary input to the second rotary control from only one side of the frame.
As will be seen, and in a preferred form of the invention, the above e) means includes a strut or link provided to extend between the secondary and primary cam mechanisms and bodily movable in response to the rotary input to said second rotary control.
Another object includes provision of the first rotary control to have input means presented at opposite sides of the frame for effecting operation of the first rotary control from either side of the door to which the frame is installed; and provision of the second rotary control to have input means presented at opposite sides of the frame, for effecting operation of the second rotary control from either side of the door to which the frame is installed.
Typically, finger and thumb operated rotors are provided at opposite sides of the frame, corresponding to opposite sides of a door carrying the frame, and are connected with the first rotary control for controlling deadbolt positioning. Also, and typically, handle levers are provided for operation at opposite sides of the frame, to be connected with the second rotary control, for controlling latch positioning. In this environment, only the lever at the inner side of the frame, and door, release both the deadbolt and door latch in response to turning of that lever.
Yet another object is to provide split-cam means to operate in conjunction with operation of the first rotary control. And a further object is to provide second split-cam means to operate in conjunction with operation of the second rotary control and displacement of the strut.
A further object includes provision of a selector means whereby turning of the handle at the door exterior optionally effects latch retraction and deadbolt retraction, simultaneously.
An added object is to provide a deadbolt actuating lever, and two cam followers associated with the lever to be displaced in opposite rotary directions, respectively, to displace the deadbolt between extended and retracted positions, and in response to operation of a primary cam defined by said primary cam mechanism.
An additional object is to provide a link having operative connection to said lever to displace the actuating lever in a rotary direction to effect extension of the deadbolt, in response to said rotary input to said second rotary control.
A further object includes provision of means responsive to reverse rotation of the first rotary control to effect latch retraction independently of deadbolt displacement.
These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:
In the drawings, a preferred multi-function door lock system or apparatus 10, has a mounting frame 11 sized for insertion into a door opening 11′.
The frame has opposite sides 12 and 13 which respectively face toward the door exterior 14, and the door interior 15. The front side 16 of the frame is carried by a mounting plate 17 held in position by fasteners 18, as seen in
A first rotary control such as rotary actuator 25 is located at one level on the frame, at the interior side of the door, for example, to control deadbolt movement between extended and retracted positions via compact mechanism in the frame. That mechanism typically includes primary cam 26. Actuator 25 is typically gripped by the user's thumb and finger, to be turned in operating the deadbolt. A second rotary control, such as handle 27 is located at a second and typically lower level, to project from the frame, at the interior side of the door, for example, to control latch 21 movement between extended and retracted positions via compact mechanism in the frame, that mechanism typically including secondary cam mechanism 28. See
Latch movement between extended and retracted positions occurs in response to turning of either of handles 27 and 32 as effected via compact secondary cam mechanism 28.
It is a feature of the invention that means is provided and operatively connected between the secondary cam mechanism 28 and primary cam mechanism 26 to effect deadbolt movement as aforesaid in response to operation of said second rotary control, as effected via rotary input to said second rotary control from only one side of the frame. Thus, for example, as interior side handle 27 is turned to turn shaft 27a, not only is the latch retracted from extended position in engagement with the door frame or associated hardware, at opening 22, (see

- 1. From extension side of door, key 29 is turning to unlock (retract) the deadbolt 19. Then handle 22 is turned to retract latch 21, to open door, and also perform this function in case deadbolt was already retracted.
- 2. From interior side of door, rotary retractor 25 is turnable to unlock (retract) the deadbolt. Also, actuator 25 is turnable to effect retraction of latch 21, via arm 61. This enables operation of the hold back 95 and 97 to enable door to swing freely.
- 3. From interior side of door, handle 27 can be turned to retract both latch and the deadbolt, as in an emergency.
